i was in the middle of installing a perrin crank pulley on my 08 wrx, little did i know it was such a pain to get the a/c compressor belt off. there is no tensioner, instead its a stretch belt. so i read a post where someone removed the bolts from the compressor to tilt it forward and get the belt on/off. i was attempting to do this when i heard a quiet "pshhhhh" coming from the line that goes from the coolant into the compressor. well, without thinking things through i felt the air coming from the place where the line and compressor meet and i went to tighten the bolt holding them together. i turned it slightly and the bolt broke and fluid sprayed everywhere. after this happened i saw a broken o-ring on the ground, so im guessing thats why it started leaking in the first place. so my questions are: is there any way i can get the dealership to fix this under warranty, especially since its a pretty minor fix? i know i wont have a/c now, but can i make a temporary fix to drive the car until i go to the dealership tomorrow?

Thats definitely an A/C line...and the coolant tank your looking at is your Engine Coolant...you might want to have a nifty excuse when you go to the dealer to explain it...I recomend you but everything back together how it was minus the pulley and just take it to the dealer and tell them your A/C doesn't blow cold air anymore

Ok I just happened to see that my coolant was low right after this happened and that line runs right behind the coolant tank so I was a bit confused since I have less than 16000 miles. How long is the. Coolant supposed to last?

Before going to the dealership, you might want to fix the problem. Here's how:
Get a new O-ring, a new bolt, and a bolt extractor from the hardware store
Extract the broken bolt
Finish the install on the pulley
Reassemble everything

When you go to the dealer, tell them that the A/C stopped blowing cold.

Btw, there is a tensioner on the A/C pulley. Whoever told you that there wasn't is an idiot. Look directly below the A/C compressor and it should be there.

or just go to a garage somewhere or have a friend help you, it's very easy to take a broken bolt out. Another thing you can not just put any normal O ring in there it has to be a "Green O Ring" they are green cause that means the support R-134a refrigerant, just a normal black O ring will not work and if the dealer notices that you have that in there they will know something is up.
